What is the effect of overusing strong hair products on the scalp?

Overusing strong hair products can lead to irritation and allergic reactions on the scalp. Many hair products contain active ingredients, fragrances, and chemicals that, when used excessively, can disrupt the natural balance of the scalp. This disruption can manifest as redness, itching, flaking, or even inflammation, resulting in an uncomfortable experience. Additionally, continuous exposure to harsh ingredients may compromise the skin's barrier function, heightening susceptibility to allergens and irritants. Therefore, moderation in the use of these products is essential to maintain scalp health and avoid adverse reactions.
